Abstract

Two sites were selected from the district of Mokokchung, Nagaland viz., Forest Regeneration Site (FRS) and Shifting Cultivation Site (SCS). At FRS, soil pH ranged from 5.00±0.13–5.50±0.04, soil moisture 35.44±1.09–53.39±0.84%, soil temperature 14.33±0.47–23.83±0.23 °C, soil organic carbon 2.20±0.08–3.03±0.02% and available nitrogen 424.48±6.73– 547.46±2.10 Kg/ha. At SCS, soil pH ranged from 5.94±0.24–6.53±0.02, soil moisture 30.32±2.64–45.72±0.98%, soil temperature 17.83±0.62–26.1±0.08 °C, soil organic carbon 1.67±0.29–2.34±0.08% and available nitrogen 324.16±8.42– 443.20±1.06 Kg/ha. Significant correlation between soil temperature, pH, soil moisture and available nitrogen was observed at FRS, while correlation of soil moisture and pH was observed at SCS. A total of 21 fungal species belonging to 13 genera were identified from the two sites. FRS had more fungal diversity than SCS. The genus Aspergillus was dominant in both the studied sites. The study observed the detrimental effect of the shifting cultivation on soil health and highlights the need for monitoring and rectification to preserve soil health.

印度那加兰邦mokokchung地区休耕对土壤健康的影响

从那加兰邦Mokokchung地区选择了两个地点，森林再生地点(FRS)和流动耕作地点(SCS)。土壤pH值为5.00±0.13 ~ 5.50±0.04，土壤湿度为35.44±1.09 ~ 53.39±0.84%，土壤温度为14.33±0.47 ~ 23.83±0.23℃，土壤有机碳为2.20±0.08 ~ 3.03±0.02%，有效氮为424.48±6.73 ~ 547.46±2.10 Kg/ha。土壤pH值为5.94±0.24 ~ 6.53±0.02，土壤湿度为30.32±2.64 ~ 45.72±0.98%，土壤温度为17.83±0.62 ~ 26.1±0.08℃，土壤有机碳含量为1.67±0.29 ~ 2.34±0.08%，有效氮含量为324.16±8.42 ~ 443.20±1.06 Kg/ha。土壤温度、pH、土壤水分与速效氮呈显著相关，而土壤水分与pH呈显著相关。共鉴定出真菌21种，隶属于13属。FRS真菌多样性高于SCS。曲霉属在两个研究地点均占优势。研究发现了轮作对土壤健康的不利影响，强调了监测和纠正以保持土壤健康的必要性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
